摘要：

本文采用膜蒸馏工艺实现对苯胺废水的处理，考察了膜污染情况，并针对污染类型考察了清洗剂种类和清洗顺序对清洗效果的影响。采用酸洗加碱洗的组合方法对膜的通量恢复率最高；在HCl质量分数为1%，NaOH质量分数为0.1%时，膜蒸馏的通量恢复到初始通量的97%，膜的接触角恢复到114.6°，为原膜接触角的96%，清洗后膜蒸馏的稳定运行时间延长至38 h。本研究为膜蒸馏处理苯胺废水的后续膜清洗策略提供了新思路。

In this article, membrane distillation process was used to treat aniline wastewater. Membrane pollution in membrane distillation process was investigated, and the effects of different cleaning agents and cleaning sequence on membrane pollution and membrane flux were investigated according to pollution types. When the mass fraction of hydrochloric acid was 1% and the mass fraction of sodium hydroxide was 0.1%, the flux recovery rate of membrane distillation was the best, which was 97% of the initial flux, and the water contact angle of the membrane recovered to 114.6°, which was 96% of the original membrane. After cleaning, the stable operation time of membrane distillation was extended to 38 h. It provides a new idea for the selection of subsequent cleaning procedures for membrane distillation treatment of aniline wastewater.
